What is the difference between mAh for external battery packs for iphone?

I want to buy an external battery pack for my iPhone 4 and I see that there are many different levels to choose from. I see packs with 1000mAh, 1800mAh, 1900mAh and so on up to 5000+mAh. My question is what difference does the mAh make in a battery pack? Is it the amount of charge it gives the phone? Is it the length of time it takes to charge? I want to be more educated before I make a purchase.

Answer:

Nnnnn Ggggg is right. i prefer a larger one, thus i can charge my phone foe more times. so convenient.
NG okorder
mAh stands for milli-Amp hours it is the capacity of the battery. A 1000mAh battery will provide 1000milliAmps for one hour. The larger the battery capacity, the longer the battery will last.
